The Ultimate Fighting Championship crowned a new light heavyweight champion Saturday night when Forrest Griffin outpointed Quinton "Rampage" Jackson in a five-round unanimous decision before a sellout crowd of 11,172 at the Mandalay Bay Events Center.

Griffin (16-4 mixed martial arts) won his first UFC title by scores of 49-46 and 48-46 twice on the judges' scorecards to become the organization's 205-pound champ.

"I won and obviously that's the best thing," Griffin said. "I'm happy with the way things turned out. But there was a lot of stuff I was planning on doing that I didn't do, a lot of things I worked on that didn't work out. I have a few ideas on things I can fix."

Griffin, a plus-200 betting underdog at the Mandalay Bay sports book, said he would agree to scheduling a rematch of the closely contested fight.

Also on the main card of UFC 86, Patrick Cote (14-4) won a three-round split decision against Ricardo Almeida (9-3) in a middleweight fight; Joe Stevenson (34-8) won by tapout via guillotine choke at 2:57 of Round 2 against Gleison Tibau (27-5) at lightweight; Josh Koscheck (14-2) beat Chris Lytle (35-15-4) by unanimous decision at welterweight; and Tyson Griffin (12-1) won a unanimous decision against Marcus Aurelio (14-6) in a lightweight bout.

Demetrious "Mighty Mouse" Johnson slammed his hands down on his UFC flyweight championship belt. Somewhere else in Rogers Arena, Rory MacDonald surely looked on with envy. Johnson and MacDonald put on dominant performances in the UFC's first trip to Vancouver in three years. Johnson defended his title for the fourth time, not allowing Ali Bagautinov to win any of their five fast-paced rounds. That couldn't quite top MacDonald, who barely let Tyron Woodley touch him in an all-important welterweight co-main event. MacDonald hopes the performance leads him to an opportunity to claim space alongside Johnson in the UFC champion's club.
